Rust

Rust is a survival game, and this database entry reports measured FPS for the AMD Ryzen 9 8945HX paired with the NVIDIA GeForce RTX 4090 Mobile. The measured dataset covers 1920x1080, 2560x1440, and 3840x2160 at Low, Medium, High, and Ultra presets, and the combo ranks 775th out of 3723 tested combos for Rust. All FPS rows are flagged as measured.

Resolution Scaling

Resolution has a clear, consistent effect in every settings tier. At Low, the average FPS is 226 at 1920x1080, 156 at 2560x1440, and 92 at 3840x2160. At High, the same resolution progression produces 128, 88, and 52. Medium moves from 152 at 1080p to 105 at 1440p and 62 at 4K. Ultra moves from 98 at 1080p to 67 at 1440p and 40 at 4K.

The 4K rows are all far below their 1080p counterparts. Low at 4K averages 92, which is above the 1080p Ultra average of 98? Actually 92 is below 98, but the two are close. 4K Ultra at 40 is the lowest average in the entire dataset, while 4K Low at 92 remains a usable row. The spread between Low and Ultra is large at every resolution, but the lower-bound result at 4K shows what happens when pixel count and shading load are both high.

This pattern indicates that the limiting component changes as resolution increases. At 1920x1080 Low, the CPU can drive a 226 FPS average. That is the highest measured result in the dataset and suggests the processor is not the bottleneck at low resolution with reduced GPU load. At 3840x2160 Ultra, the average falls to 40, which is far below the 1080p Ultra result of 98. The GPU becomes the dominant limiter once resolution and preset load climb. The data is consistent with a configuration that has very high CPU headroom and a GPU that is strong but still constrained by 4K rendering work.

CPU Role

The AMD Ryzen 9 8945HX is a 16-core, 32-thread processor in the 8000 series, using Zen 4 architecture on the Dragon Range platform. It has a base clock of 2.50 GHz and a boost clock of 5.40 GHz. The L3 cache is 64 MB, and the processor supports DDR5 memory with dual-channel bandwidth of 83.2 GB/s. The CPU is built on TSMC 5 nm and has a TDP of 55 W.

In synthetic benchmarks, this CPU scores 42713 in Cinebench R23 multi-core and 6030 in Cinebench R23 single-core. It also scores 51405 in PassMark multithread and 3907 in PassMark single-thread. The average benchmark score is 76212, placing the CPU at the 95th percentile versus all CPUs. The nearest rivals by average score are the Intel Core Ultra 9 285HX at 76155 with a deltaPct of 0.1, the AMD EPYC Embedded 8224P at 76492 with a deltaPct of -0.4, the AMD Ryzen Threadripper PRO 9945WX at 76513 with a deltaPct of -0.4, and the AMD Ryzen 9 9950X3D at 75779 with a deltaPct of 0.6.

These numbers place the 8945HX in a tight group near the top of the general CPU database. The high single-core Cinebench score of 6030 and PassMark single-thread score of 3907 align with the measured 1080p Low result of 226 FPS, which is the highest average FPS in this Rust dataset. The 16-core and 32-thread design also provides large multi-threaded throughput, with a Cinebench R23 multi-core result of 42713 and a PassMark multithread result of 51405. For Rust, the CPU appears to be feeding the GPU effectively at lower resolutions and higher framerates.

GPU Role

The NVIDIA GeForce RTX 4090 Mobile is based on the AD103 chip with Ada Lovelace architecture, built on TSMC 5 nm. It has 9728 shading units, 304 texture mapping units, 112 ROPs, 76 ray tracing cores, and 304 tensor cores. Base clock is 1335 MHz, boost clock is 1695 MHz, and memory runs at 2250 MHz with 18 Gbps effective data rate. The memory subsystem consists of 16 GB GDDR6 on a 256-bit bus, providing 576.0 GB/s of bandwidth. The GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and connects over PCIe 4.0 x16.

Synthetic scores include 27212 in PassMark G3D, 12347 in PassMark GPU compute, 180831 in Geekbench OpenCL, and 170774 in Geekbench Vulkan. The average benchmark score is 43667, placing the GPU at the 84th percentile versus all GPUs. The nearest rivals by average score are the NVIDIA Quadro M6000 at 43301 with a deltaPct of 0.8, the NVIDIA GeForce RTX 5050 Mobile at 43268 with a deltaPct of 0.9, the NVIDIA Quadro M6000 24 GB at 43262 with a deltaPct of 0.9, and the NVIDIA RTX A6000 at 44075 with a deltaPct of -0.9.

In the Rust measurements, the GPU’s behavior is visible in the settings scaling. At 1080p, Ultra is 98 FPS and High is 128 FPS, while at 4K, Ultra is 40 FPS and High is 52 FPS. The 4K Medium row averages 62 FPS with min 52 and max 71, making it the only 4K preset with min/max data. The 16 GB VRAM capacity and 576.0 GB/s bandwidth are substantial, but the 4K Ultra result shows that even this GPU cannot maintain high average FPS at maximum settings with this CPU.

Measured FPS Breakdown

The full measured FPS set is listed below. Only the Medium preset rows include min and max FPS values in the data; the other rows have null min/max fields.

At 1080p, the Low preset is far ahead of every other row, with an average of 226. Medium reaches 152 with min 129 and max 175, High reaches 128, and Ultra reaches 98. At 1440p, Low averages 156, Medium 105 with min 89 and max 120, High 88, and Ultra 67. At 4K, Low averages 92, Medium 62 with min 52 and max 71, High 52, and Ultra 40.

The Medium rows are the only ones with frame range data, and they show that the minimum FPS stays within a reasonable distance of the average. At 1080p Medium, min 129 and max 175 surround an average of 152. At 1440p Medium, min 89 and max 120 surround an average of 105. At 4K Medium, min 52 and max 71 surround an average of 62. For presets without min/max values, the database only provides averages.

How This Combo Ranks

The combo holds rank 775 out of 3723 tested combos in Rust. That places this CPU/GPU pairing in the upper portion of the database, though not at the top. The general component percentiles are also useful context: the Ryzen 9 8945HX is at the 95th percentile among all CPUs, and the RTX 4090 Mobile is at the 84th percentile among all GPUs.

The Rust-specific rank is not identical to either component’s general percentile. The CPU’s average benchmark score of 76212 is essentially tied with several high-end rivals. Among those rivals, the Intel Core Ultra 9 285HX is closest at 76155 with a deltaPct of 0.1. The AMD EPYC Embedded 8224P and AMD Ryzen Threadripper PRO 9945WX both sit at -0.4 deltaPct, and the AMD Ryzen 9 9950X3D sits at 0.6 deltaPct. On the GPU side, the RTX 4090 Mobile’s average score of 43667 is within 0.9 deltaPct of the NVIDIA Quadro M6000, the NVIDIA GeForce RTX 5050 Mobile, and the NVIDIA Quadro M6000 24 GB, while the NVIDIA RTX A6000 is -0.9 deltaPct away.

Given these positions, the rank of 775 out of 3723 reflects Rust’s specific response to this combination. The measured FPS rows show a system that is strongest at 1080p and still competitive at 1440p, with 4K available but requiring lower presets to maintain higher averages.

Settings Recommendations

The measured rows provide a clear preset ladder. At 1080p, Low is the fastest at 226 FPS, but High at 128 FPS offers the best combination of a higher visual preset and a strong average. Ultra remains playable at 98 FPS, though it is lower than High by a large margin. Medium at 152 FPS sits between them with min 129 and max 175.

At 1440p, Low averages 156 FPS and Medium averages 105 FPS with min 89 and max 120. High drops to 88 FPS, and Ultra drops to 67 FPS. The Medium row at 1440p is the strongest balance in the measured data for this resolution: it keeps the average in triple digits while staying above the High and Ultra averages. If raw framerate is the priority, Low at 156 FPS is the clear choice.

At 4K, Low is the fastest preset at 92 FPS. Medium averages 62 FPS with min 52 and max 71, while High and Ultra fall to 52 FPS and 40 FPS respectively. For 4K use, Low is the speed-oriented preset, and Medium is the highest settings tier that still produces a documented min and max around 52 and 71.

Overall, the measured FPS set indicates that 1080p High at 128 FPS is the best experience for high framerate with a higher preset level. 1440p Medium at 105 FPS is the best experience for users who want more resolution while keeping a strong average. 4K Medium at 62 FPS is the best measured 4K option when preset fidelity matters more than raw speed.
